Here's to hoping Floyd Mayweather and Robert Guerrero have both been counting their calories.

The two fighters are set to weigh in on Friday, which is the final event in the buildup to their fight on Saturday night.

Here is the key info you need to know going into the event.

When: Friday, May 3 at 6 p.m. ET

Where: MGM Grand Garden Arena, Las Vegas

Watch: Showtime, CBS Sports Network

The biggest question going into this weigh-in will be exactly where Guerrero will come in at. According to David P. Griesman of BoxingScene.com, Mayweather should likely have no problem as his most recent weigh-in had him at 148.5 points. Guerrero had a slightly tougher task ahead of him as he needed to drop six pounds in order to come in at the 147-pound limit.

Considering he's a professional athlete, Guerrero should have no problem getting there. With so much money to be lost by failing the weigh-in, you're not going to see either fighter fail to make weight. Mayweather will likely be the lighter one of the two considering he has had less weight to lose, and being lighter will help him move around the ring more.

Most of the fun will come from how the two fighters interact with one another, though, it's not like anything will be able to top what Guerrero's father, Ruben, said about Mayweather during the pre-fight press conference on Wednesday.

Those are some pretty harsh words, and you could see Mayweather just biting his lip the entire time. He may address the issue further at the weigh-in, but he'll likely let his work in the ring do the talking.

Sure there could be some sort of altercation at the weigh-in. Guerrero, though, has already stated that he won't hesitate to knock down Mayweather if Money gets physical in any way.

At this point, though, it's doubtful either fighter would do anything to jeopardize the fight, which is just a day away.

This is the last chance for the promoters to convince those on the fence to buy the fight.

But really, there's already a lot of hype going into this fight. It's Mayweather's first fight in over a year. Although Guerrero isn't a high-profile opponent, Money May is good enough at self-promotion to offset that.

There's the boxing fans who will want to see if or how much Mayweather has fallen off at all during his time out of the ring. Then, the more casual fans will want to see somebody finally knock out the loudmouth braggart Mayweather ensures a captivated audience for this fight.
